Reactions of HBr+ ions in the 2Πi, v+ quantum states with H2 and HBr molecules

The mechanisms and kinetics of low-temperature ion-molecular reactions between the Br + , HBr + , and DBr + ions and the HBr, DBr, H 2 , and D 2 molecules were studied. The HBr + ( i , v + ) and DBr + ( i , v + ) ions were prepared in separate spin-orbit ( i ) and vibrational ( v + ) states by reson...

Description
Summary:The mechanisms and kinetics of low-temperature ion-molecular reactions between the Br + , HBr + , and DBr + ions and the HBr, DBr, H 2 , and D 2 molecules were studied. The HBr + ( i , v + ) and DBr + ( i , v + ) ions were prepared in separate spin-orbit ( i ) and vibrational ( v + ) states by resonance multiphoton ionization in a free flow of halogen halides (HBr and/or DBr) with hydrogen, deuterium, or inert gases (Ar, He). The effectiveness of various reaction channels, including the exchange of charges, H and D atoms, and H + andD + ions, was studied. The quantitative data on the kinetics of these reactions were obtained for separate quantum states of the ions. The resonance ionization of one of the two ion isotopomers H 79 Br + (D 79 Br + ) or H 81 Br + (D 81 Br + ) was used to study and compare the effectiveness of various ion-molecular reaction channels.
